Borussia Dortmund's 2-1 comeback win over RB Leipzig to snap a three-game losing run was a reward for their hard work, coach Nuri Sahin said.

Dortmund, who face Sturm Graz in the Champions League next week, were without nine injured players but dug deep to score twice after visitors Leipzig took the lead.

They came into Saturday's Bundesliga match against second-placed Leipzig having lost three straight games across all competitions, and fell behind to Benjamin Sesko's thumping strike.

But goals from Maximilian Beier and Serhou Guirassy completed the turnaround and saw Sahin continue his strong home form, having won each of his first five league matches in charge at Signal Iduna Park.

"An important win, and in my opinion a deserved win," Sahin told reporters. 

"We started well and the goal did not knock us down. We were rewarded with a goal before half-time and then again after the break. Sometimes you suffer, but with suffering you learn. We are now on a better track and won't veer away."

Sahin had been under mounting pressure following a loss in the Champions League to Real Madrid after leading 2-0, and defeats by Augsburg in the Bundesliga last week and Tuesday's DFB-Cup exit to Wolfsburg.

"On Tuesday I also saw a team that gave everything but were not rewarded in the end. Today we were," Sahin said.

"The boys applied what we planned. The belief in this team is the same even if we had lost seven in a row."

Late goals from Robert Andrich and Patrik Schick helped Bundesliga leaders Bayer Leverkusen hit back from behind to beat Hoffenheim 2-1 and keep their unbeaten season intact.

Xabi Alonso’s men looked set to slip to their first defeat of the campaign after brilliant skill from Maximilian Beier gave the visitors the lead in the 33rd minute.

The hosts, boosted by the news this week that Alonso has decided to stay at the club, hunted for an equaliser with Hoffenheim keeper Oliver Baumann making a string of superb saves.

Borja Iglesias hit a post for Leverkusen after 87 minutes but they finally made their breakthrough moments later when Andrich lashed home a bobbling effort from the centre of the box.

The goal was good enough to extend their record unbeaten run to 39 games but Alonso’s side wanted more and they snatched the three points in the first minute of injury time.

The ball was played to the right flank where Nathan Tella delivered a cross behind the Hoffenheim defence and Schick reacted fastest to volley home from close range.
